A cigarette filter-triboelectric nanogenerator (CF-TENG) which generates triboelectric power. The cigarette filter-triboelectric nanogenerator (GF-TENG) includes a positive triboelectric material made from recycled cigarette filters (CFs) and a negative triboelectric material made from plastic waste, wherein the cigarette filters were mixed with conductive materials. The cigarette-filter triboelectric nanogenerator (CF-TENG) device exhibits excellent electrical output performance.

In a process for transforming waste material into useful material, a quantity of waste material such as household garbage or municipal solid waste is provided. The waste material is pre-shredded into pre-shredded waste material. The pre-shredded waste material is processed to at least partially remove one or more selected material components, thereby providing a processed pre-shredded waste material. The processed pre-shredded waste material is then secondarily shredded into secondarily shredded waste material which is then hydrolyzed under pressure greater than ambient pressure to create an aggregate cellulose pulp.

A biosolids treatment system that treats human biosolids to produce thermal energy for self-consumption for the production of beneficial use products including low carbon ash, high carbon activated biochar, and Class A biosolids. The system includes a variable feed conveyor that conveys a biosolid feed into a dryer; a dryer that dries the biosolid feed to a predetermined moisture content to create one of a beneficial use products, where the predetermined moisture content is controlled by varying the speed of variable feed conveyors and a variable feed mixer; and a gasifier that converts the biosolid feed into two of the beneficial use products.

A process for transforming a stream of MSW material into feedstock for an anaerobic digester and the resulting generation of biogas and other useful products includes the removal of one or more selected chlorine containing components and the retaining of substantially all paper components. At least 70% by mass of the incoming stream of MSW material is hydrolyzed and subsequently directed to the anaerobic digester.

The pelletizing facility (100) according to the present invention allows the manufacture of solid recovered fuel pellets from municipal solid waste without separating parts of the municipal solid waste before starting the pelletizing process. Thus, a higher amount of the municipal solid waste can actually be used to manufacture solid recovered fuel pellets. The pelletizing facility (100) as well as the method according to the invention can be used in particular to manufacture solid recovered fuel pellets that can be used in the production of hydrogen and/or carbon dioxide enriched syngas by a torrefaction of the solid recovered fuel pellets with a subsequent gas treatment.

[Problem] To provide a method for producing useful substances, which converts organic waste containing heavy metals into harmless substances such as fertilizers and soil conditioners by carbonizing organic matter while detoxifying heavy metals.

[Solution] The present invention is a method for producing a useful material, said method comprising treating an organic waste in which heavy metals are mixed to produce a carbonized material containing weighed material. The organic waste in which the heavy metals are mixed is treated by dry carbonization of an organic waste to which a Ca component starting material and a SiO.sub.2 component starting material, which are topalmorite starting materials, are added in amounts sufficient to contain the mixed heavy metals in topalmorite crystals; a charcoal-forming step of dry carbonizing the waste, carbonizing the organic waste to form a carbide; the carbide formed in this carbide forming step and the topamolite raw material are charged into a reaction vessel while maintaining the high temperature state in the previous step, and slowly cooled in the presence of water with stirring to form the organic material; a heavy metal confinement step of forming a topamolite crystal mineral in which heavy metals mixed in the organic waste are confined, and forming a slurry in which the carbide and the topamolite crystal mineral are dispersed; and drying or dehydrating the slurry formed in the previous step to produce a useful substance containing a carbide containing the topamolite crystal mineral.

The present invention relates to an organic waste treatment apparatus consisting of a garbage receiving unit, a probing door, a garbage compactor unit, a crushing unit fixed to the upper part of the structure frame, a mixing unit positioned underneath the crushing unit, a motor that drives all movements of the apparatus using belt drive and gear drive, and a control panel controlling the functions of this device.

A method and an apparatus for waste processing of mixed waste comprising an organic compostable waste portion and an organic non-compostable waste portion are disclosed. The apparatus comprises a shredder unit for shredding a load of mixed waste, a composting unit providing a microbial environment for composting the food waste portion of the mixed waste load, a heating unit providing a heating environment for heating the inorganic waste portion to a temperature higher than in the composting unit, and a control unit for controlling a moisture level of the mixed waste load in the heating unit. When the target moisture level is reached the shredded, composted and dried mixed waste load is transported to an exit unit for optional further processing as refuse derived fuel.
